C. H. WEBER MUSIC LEAF TURNER Filed March 22 1923 Patented June 3, 1924.

UNITED STATES CHARLES H. WEBER, OF COLUMBUS, OHIO.

MUSIC-LEAF TURNER.

Application filed March 22, 1923. Serial No. 626,722.

To all whom it may concern:

Be it known that 1, CHARLES H. WEBER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specifioation.

The present invention is directed to improvements in music leaf turners and has for its object to provide a device of this character constructed in such manner that it can be supported upon the fall board'of a piano and in such position thereon to permit the turning of a music leaf without the necessity of the performer removing the hands from the key board.

A further object of the invention is to provide a device of this kind so constructed that the music leaf will be effectively supported and held against tilting or bending while the music is being played.

With these and other objects in view, as will appear as the description proceeds, the invention consists in the novel features of construction, combinations of elements and arrangements of parts, and hereinafter to be fully described and pointed out in the appended claims.

In the accompanying drawing:

Figure l is a front view of a piano showing the device in place thereon,

Figure 2 is an enlarged view of the device Figure 3 is a sectional view'on line 33 of Figure 2,

Figure 4 is a sectional view on line 4-4 of Figure 2,

Figure 5 is a sectional view on line 55 of Figure 2, and

Figure 6 is a detail view of the shifting lever.

Figure 7 is: a sectional view on line 7--'(' of Figure 2.

Referring to the drawing 1 designates the fall board of a piano which is as usual provided With a bottom rest 2 and upon which the device is supported. A frame 3 is provided and has its lower rail 4 provided with a channel member 5, the purpose of which will appear later.

The frame further includes a vertical bar 6 upon which is supported a post 7, the upper end of which is provided with an offset 8 ada ted to detachably receive the hook 9, said liook having secured thereto an elastic connection 10 and to the lower end of which is secured a cord 11, the lower end v of said cord being fixed centrally of a clamp- 7 respectively with the bracket 13 and shaft 15, while the vertical arm 19 of said frame has secured thereto clips 20, which are adapted to engage the outer edge of a music leaf 21. This music leaf is associated as usual with the front and back pages 22 and 23 of a music sheet and it is desired to turn this sheet 21 conveniently as desired.

Fixed to the left hand end of the member 5 is a bracket 24 in which is adjustably mounted a screw shank 25 and to the inner end of which is secured one end of a coil spring 26 and to the inner end of this spring is secured a cord 27 which is partially wound around the pulley 16, the purpose of which will appear later. Also fixed to this pulley and partially wound therearound is a cord 28, the same being of such length as to extend over the right hand end of the piano 29, and in order to permit this cord to operate, an arm 30 is pivotally connected with the right hand end of. the bar 4 and this arm is adapted to project beyond one side of the piano and is provided with a guide pulley 31 and over which the cord 28 travels.

Pivotally mounted beneath the key board of the piano is a transversely disposed lever 32, the outer end of which has pivotally connected thereto an arm 33 and connected to the inner end of the lever 32 is the terminal of the cord 28 which is trained around a pulley 34 carried by the outer end of the strip 35 which. is fixed in any suitable manner beneath the key board of the piano and to which the lever 32 may be pivoted.

In operation the front and back sheets 22 and 23, are placed in the channel of the member 5 after which the clamping bar 12 is placed in said channel thus clamping the front and back sheets, after which the leaf 21 is engaged with the clips 20, and since horizontal swinging of the lever 32 will pull upon the cord 28 it will be obvious that the pulley 16 will be rotated, thus causing the shaft to rotate and consequently swinging the frame 17 to the left, thus turning the leaf'21 so that the reverse side of leaf 21 and I the front face of the back leaf 23 can be plainly viewed. It will-be of course obvious position after which the bar 12 is removed 15' and a new piece of music supplied. It will be observed that the cord 11 will lie in the crease between the sheets 22 and 23 thus preventing these sheets from tilting for- 'wardly; and

service. It-willbe of course understood that the "knee of the player can be pressed into enowing to the elastic connection I 10 this string will be held taut for efiicient gagement with the arm 33 to swing the lever 32 when desired.

What is claimed is:

1; A music leaf turner comprising a frame, a channel member associated with the frame, a leaf engaging frame pivotally connected with said frame, a clamping bar detachably' engaged in the channel member for engaging certain music sheets, and means for swinging the leaf engaging frame. a

2. A music leaf turner comprising a supporting frame pivotally connectedwith said frame, a. clampingbar detachably engaged in the channel of said member, a pulley connected with the leaf engagingframe,

vand means for rotating the pulley to swing said leaf engaging frame, said clamping her being adapted to hold certain sheets within the channel of said member. w e V p In testimony whereof I affix my signature. I CHARLES WEBER.
